As a US Colony they are not free to trade with, set tariffs or negotiate trade deals with other countries, unless approved under US Law. They have to abide by any trade restrictions and tariffs that applies to any other US State or territory. (There are many and more is likely to come)
They may be free to buy whatever they want from whomever the want, at least in theory, but for all practical purposes it is not that easy. They are under US jurisdictions and has to comply with US restrictions. (see above)
As for shipping it by whatever means they want; yes, if in large enough quantity and regularity to entice shipping companies to call there. For all practical purposes it is done through US ports because that is to/from where regular shipping lines are available.
Short term waiver is not an issue. I raised the questions in Post #7 to get an understanding of how important the PR trade is to overall Jones Act trade and how much the actual impact on the PR economy and consumers are.

Having lived on a much smaller island that reluctantly became an independent country, I have watch the process of nation building with no natural resources and against all odds.
Singapore succeeded beyond all expectations, but that was due to honest and good governance, which doesn’t appear to be the case in PR at this time.
Could a strong leader with the aptitude and leadership qualities that was the case with Lee Kuan Yew be found to lead an independent PR???
